plot_surface不在matplotlib

Question

我正在尝试在matplotlib中的FancyBboxPatch前面绘制一个球体。但是，球体被FancyBBoxPatch覆盖。我的最小工作示例如下：

 #!/usr/bin/env python3                                                                                                                                                                                      

 import numpy as np
 import matplotlib.pyplot as plt
 from matplotlib.patches import FancyBboxPatch
 from mpl_toolkits.mplot3d import Axes3D
 import mpl_toolkits.mplot3d.art3d as art3d

 if __name__ == '__main__':

     fig = plt.figure()
     axes = fig.add_subplot(111, projection = '3d')

     for i in range(7):
         for j in range(7):

             box = FancyBboxPatch((i, j),
                                  1, 1,
                                  boxstyle = 'square,pad=-0.1',
                                  edgecolor = (0.333, 0.333, 0.333),
                                  facecolor = (0.333, 0.333, 0.333))
                                  #zorder = 0)                                                                                                                                                               

             axes.add_patch(box)
             art3d.pathpatch_2d_to_3d(box, z = 0, zdir = 'x')

     u = np.linspace(0, 2 * np.pi, 100)
     v = np.linspace(0, np.pi, 100)
     x = 0.3 * np.outer(np.cos(u), np.sin(v))
     y = 0.3 * np.outer(np.sin(u), np.sin(v))
     z = 0.3 * np.outer(np.ones(np.size(u)), np.cos(v))

     surface = axes.plot_surface(x + 1, y + 1, z + 5, color = 'red')
                                 #zorder = 100,                                                                                                                                                              
                                 #alpha = 1)                                                                                                                                                                 

     axes.set_xlim3d(0, 14)
     axes.set_ylim3d(0, 14)
     axes.set_zlim3d(0, 14)

     plt.show()

产生情节：

在图中，球体完全由FancyBboxPatches覆盖。

正如你在脚本中被注释掉的部分所看到的，我已经玩了关键字参数“alpha”和“zorder”（我不想改变FancyBboxPatches的alpha）来尝试制作球体绘制在FancyBboxPatches之上，但是不成功。

如何在FancyBboxPatches前面绘制球体？或者答案是否与Matplotlib 3D plot zorder issue类似，我应该尝试MayaVi？
